Hi yes SK has a No Boid rule as per their provincial laws.
AB is pretty much regulated by provincial laws but they are fairly straight forward & Calgary does not have any "silly bylaws".
Main AB laws for snakes are are no venomous or large Boids such as Rocks, Retics, Anacondas, Scubs, Burms etc. or any of the dwarf species of such or hybrids of them. Also things like no Western Hognose (native species) & for those into breeding their own prey live rats are illegal here as well.
Dead FT ones are fine but huge legal issues if caught with live rats.
You will have no issues keeping your Boas here anyways, Mark
